<p><strong>Does snap-pac backup non-btrfs /boot partitions?</strong></p>
|
|
<p>No, but you can add a hook that does it for you. It would be something like the following:</p>
|
|
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>[Trigger]
|
|
Operation = Upgrade
|
|
Operation = Install
|
|
Operation = Remove
|
|
Type = Package
|
|
Target = linux
|
|
|
|
[Action]
|
|
Description = Backing up /boot...
|
|
When = PreTransaction
|
|
Exec = /usr/bin/rsync -avzq --delete /boot /.bootbackup
|
|
</pre></div>
|
|
</div>
|
|
<p>Note that you will probably want to name the file with a numbered prefix less than
|
|
<code class="docutils literal notranslate"><span class="pre">05</span></code> so that it is run before the snap-pac pre snapshot takes place. That will ensure
|
|
that the snapshot taken will have the boot partition back-up corresponding with the
|
|
state of the system. For example, you could name it <code class="docutils literal notranslate"><span class="pre">04-backupboot.hook</span></code>.</p>
|
|
<p><strong>How do I link old kernel modules automatically when the kernel is upgraded?</strong></p>
|
|
<p>This behavior is no longer a part of this package. Use a pacman hook like the following:</p>
|
|
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>[Trigger]
|
|
Operation = Upgrade
|
|
Operation = Install
|
|
Operation = Remove
|
|
Type = Package
|
|
Target = linux
|
|
|
|
[Action]
|
|
Description = Symlinking old kernel modules...
|
|
When = PostTransaction
|
|
Exec = /usr/bin/bash -c "find /usr/lib/modules -xtype l -delete; ln -sv /.snapshots/$(snapper -c root list | awk 'END{print $1}')/snapshot/usr/lib/modules/$(uname -r) /usr/lib/modules/"
|
|
</pre></div>
